fredd [130]

A quarter each is 25 cents. And a dime each is 10 cents. counts from 10 10 times and then add 25 4 times and you get 200 which is 2 dollars. Example: 10 20 30 40 50 60 70 80 90 100 with 10 dimes alone that's a dollar 4 quarters equal another dollar so both of those equal 2 dollars. Layla had 4 dimes and 4 quarters when she added 6 more dimes it all equaled 2 dollars. Hopefully this makes sense.

Solve the following system of equations. 2x + y = 3 x = 2y - 1 Make sure there are NO SPACES in your answer. Include a comma in
mrs_skeptik [129]

Answer:  x=1;y=1 or (1,1)

Step-by-step explanation:

You can apply the Method of substitution.

Knowing that  x = 2y - 1 (second equation), you can substitute it into the first equation and solve for the variable y:

2x+y=3\\2(2y - 1)+y=3\\4y-2+y=3\\5y=3+2\\5y=5\\y=1

Now you need to substitute y=1 into the second equation x = 2y - 1 to calculate the value of the variable x. Then:

x = 2(1) - 1\\x=2-1\\x=1

Then, the solution is:

x=1;y=1 or (1,1)
